Question

Find the average rate of change of a function that contains the points (-2,3) and (2,5). -2, -1/2, 1/2, 2

Answer 1

Answer:

The answer is "$\frac{1}{2}$".

Step-by-step explanation:

Given points:

$(-2,3)\\\\(2,5)$

average rate=?

$x_1=-2\\\\y_1=3\\\\x_2=2\\\\y_2=5$

$average\ rate=\frac{y_2-y_1}{x_2-x_1}$

                     $=\frac{5-3}{2-(-2)}\\\\=\frac{5-3}{2+2}\\\\=\frac{2}{4}\\\\=\frac{1}{2}$
